Since the beginning of time, or at least as long as the Sondek has been
around Ivor Tiefenbrun and Linn dealers have recommended only a light and
rigid shelf below the LP12 for best sonic results.
I understand testing a theory because so little is absolute yet, when the
designer and builder calls for a specific foundation, maybe there is something
There is not a TT on earth made to withstand "When I place the
arm/cartridge on a (stationary) LP, the entire arm board and arm rest
resonates to light finger taps, and the sound emerges as rather loud thuds
through the speakers, at normal listening levels.' this is not a valid test of TT
resonance mismanagement... sorry.
Personally I have found most suspension TT's to give excellent results with
the same (a light rigid shelf).
The Ikea Lack is such a table.
